A) 8x + 40
B) x + 5
C) 8(x +10)
D) x + 8

Answer 1

C

Explanation:

Because if you add the variables that are the same it would be 2+6=8 & 5+5=10. Now you have to put it in an equivalent equation which would be 8(x+10).

Answer 2

A) 8x+40

`2(x + 5) + 6(x + 5) =`

`2x + 10 + 6x + 30 =`

`8x + 40`
